Applied Materials (AMAT), the nation’s biggest maker of semiconductor-fabrication equipment, has one of the richest dividend yields among major technology companies., including Microsoft (MSFT), Intel (INTC), Hewlett-Packard (HPQ), Oracle (ORCL) and Apple (AAPL), which later this summer begins paying a quarterly dividend.

Why? For one thing, despite some hefty investments, Applied Materials has had only limited success as a maker of equipment for companies that manufacture silicon-based solar-cell products; that adjacent market hasn’t fulfilled expectations so far.

For another, Applied Materials’ orders tend to lag the chip sector. Chipmakers are having a good run currently, with booming orders from smartphone and tablet makers driving higher volume. Now, as their chip “foundries” begin to run at close to full capacity, and as new designs require new production tools, semiconductor makers are ordering more of the chip-making equipment Applied Materials sells.

Applied Materials has been reducing shares outstanding, and announced a new $3 billion stock buyback program in March. That’ll give per-share earnings a little extra help.

As low interest rates have squelched many avenues for income investing, more investors are focusing on dividend stocks. Whenever we invest in a company for its dividend, of course, we’re also buying its underlying shares.
